Winter weather has been exceedingly unpredictable lately, and 2023 is shaping up to be no different. For homeowners, sudden dips in temperature or predictions of ice, snow and freezing rain could predict damage to the trees in your landscape. Trees react to winter weather by going dormant, allowing them to acclimate to colder temperatures. In short, they stop growing, and sap, the lifeblood of trees, stops flowing. During this time, the membranes of a tree’s cells become more permeable and flexible, so they are better able to handle the sharp edges of frozen water molecules if those molecules happen to make their way through the cell wall.
Coniferous trees have many adaptations that help them survive the chill, such as long needles with a smaller surface area to stop snow build-up and control water loss. They also have waxy coatings on the needles that prevent loss of moisture and help keep them from drying out. Some trees even produce proteins that help prevent the formation of ice crystals. However, not every tree will survive a cold snap without damage, so it’s important to know how to treat tree damage from winter storms if it happens.
What Does Tree Damage Look Like and How Do You Manage It?
There are several ways winter storms can damage trees. Roots and branches can be cracked by fluctuations in temperatures. Ice and snow accumulation can damage branches, causing breakage and loss. Ice can also cause trees to become brittle and can even crack branches or trunks.
The accumulated weight from heavy snow and ice can deform or break branches, although it can also insulate the tree if the plant is completely covered. Strong winds from winter storms can dry conifer needles, dry or winter burn branches and roots, break branches, and – in extreme conditions – uproot trees. Tree health can be altered or severely damaged by drying salt sprays, sodium chloride, or other deicers that may be placed on roadways, driveways, and sidewalks and potentially runoff from there. These substances can alter the composition of the soil and cause excessive drying of roots, bark, stems, and needles.
What Does Winter Storm Damage Look Like?
Winter storm damage can show up in many ways depending on the storm event, what caused the damage (ice, snow, wind, temperature fluctuations, chemical), and what tree is affected. In general, the following can be signs of tree damage:
- Heavy loading, deformed, or hanging branches or stems
- Detached or broken branches
- Compression cracks on trunks, branches, or stems
- Dead, dying, and discolored needles on conifers
- Dead, dying, and discolored leaves on deciduous plants in spring
- Tree leans or up-heaving of roots
If you notice any of these signs, you should take care of the issue immediately for safety and the continued health of your trees.
What Can You Do if You Spot Storm Damage?
If you suspect a tree is damaged by winter weather, take precautions. Do not walk under the affected tree. Wear personal protective equipment (PPE) such as a hard hat if you go near it to assess the damage. If you can, wait until the snow or ice has melted before turning your attention to the tree. Then, clear any branches that have fallen and remove any broken or detached branches that you can reach from the ground. If your trees are bowed by an accumulation of ice or snow, leave them alone. Do not, however, shake a tree to try and remove snow, as this can break fragile branches or cause further damage. Do not try to melt snow by spraying trees with water, as the water may freeze to ice and cause more problems. Healthy trees will recover in the spring. If you believe the tree is irreparably damaged, you should consult with a certified arborist to discuss your options.
In early spring, you can consult with a certified arborist to discuss your options for corrective pruning and/or removal of jagged branch parts and broken or detached branches.

How to Protect Your Trees from Frost
Weather shifts can range from unexpected frosts in the late spring or early fall to unexpectedly warm weather during this period that can get trees growing before all chance of frost has passed.
When is the Best Time for Tree Trimming?
If you have trees in your yard, you know that they can sometimes look overgrown and in need of some shaping. But choosing the best time for tree trimming is critically important. Trimming trees at the wrong time can be detrimental to tree health, but the answer is not always straightforward. Many factors go into deciding whether you should trim, such as the type of tree, whether it has insect or other damage and other issues in the surrounding landscape that may be affecting the tree’s health.
How Can I Tell if a Tree is Weak?
It should go without saying, but trees have a huge impact on our lives. Whether it's building a tree house as a child or planting a maple to increase property value as an adult, trees provide a seemingly endless list of benefits. And while many of us have spent summers swinging on hammocks hung from beautiful trees like venerable oaks, when was the last time you considered the health of the tree before you started relaxing? And while it seems like a large tree is stronger than steel, we need to make sure they're taken care of and healthy so we can enjoy them long into the future. So, how can we determine when a tree is unsafe and losing its strength?
